ka throttle body on sr (cruise control) questions

[devonkyle77]

ok ive gota dohc ka tb going on an s14 sr, so i can keep cruise control.one thing i have noticed, is that the sr throttle body inner diameter is much smaller. will the larger inner diameter create a problem, as i am running a very oem setup.also the way the hoses hook up is different.finally, the throttle position sensors are different, which i guess means i will need to be splicing wires?can anyone shed some light on this?it just seems the writeup about this was so vague, and made no mention of these things i have noticed.

The S14 SR Throttle Body is indeed smaller than the KA24DE TB. The S14 SR and S15 SR TB's are the same size. The S13 SR TB is the same size as the KA TB, I think. The info is here somewhere.

As for the cruise control, I used a SR20DE from an automatic G20, which has the same diameter and the wiring connections are the same as my automatic S13 SR TB. The manual SR TB has different wiring and connectors than the automatic.
